The remains of the world’s oldest planned city may crumble to dust in twenty years if action isn’t taken, the Telegraph reports.

Mohenjodaro, a 5,000 year-old city in Pakistan, is under threat from extreme temperatures and monsoon rains, which leave deposits of salt on the unbaked clay bricks that were used to create its buildings. That salt leeches out any moisture in the bricks and slowly turns them to dust.

A crew of workmen is coating the ancient structures with salt-free mud, but there are far too few people on the job and very little money.

The Bronze Age city, which is a UNESCO World Heritage Site, was founded around 3,000 BC and shows a remarkable amount of urban planning. There were toilets in every house, separate water systems for drinking and sewage, roads laid out on a grid system, a large communal bath shown in the above photo, and a communal granary. It was the center of the Indus Valley civilization and traded as far away as Mesopotamia, using a set of standardized weights and measures to regulate commerce.

UNESCO officials met with Pakistani archaeologists last week to draw up a plan to save the site, which includes burying some of the most threatened structures. It remains to be seen whether Pakistan’s government, strapped for cash and stuck in a grueling war with the Taliban, will foot the bill.

I visited Mohenjodaro back in 1994 when Pakistan was safer to visit than it is now and found the place to be enchanting. The layout can be clearly seen and it almost feels like you’re in a living city. It would be a shame if such a landmark of human development disappeared.

Do you ever feel nervous going through border control in a new country? How about when you return home? A study by IXP visas polled 1,000 travelers who had been to at least ten foreign countries; over 60% said they felt intimidated by border officials at some time, with the most intimidating vote going to American border control. The reasons sited for the nerves included “obvious weaponry on display,” a “lack of humor,” and a general “intimidating demeanor.”

The countries with the most intimidating border officials:

USA: 22% (of respondents called border control officers intimidating)

UAE: 12%

Mexico: 9%

Canada: 8%

South Korea: 6%

UK: 5%

Israel: 5%

Pakistan: 4%

Venezuela: 4%

Cuba: 3%

Have you felt intimidated entering (or re-entering) the U.S.? Which country has you most nervous at immigration?

The Henley & Partners Visa Restriction Index ranked countries around the world based on how freely their citizens could travel with just a passport. The United States came in 2nd place, tying with Denmark, Germany and Luxembourg. American citizens can enter 172 countries without having to worry about red tape, according to the study.So what is the best passport to have? A British, Swedish or Finnish passport is as good as it gets, giving passport holders access to 173 foreign destinations visa-free. In general, being a member of an EU country helps a lot if you want to travel spontaneously, with nine out of 10 of the top countries all part of the European Union.

Some countries however, are not so lucky, with citizens in Lebanon, Nepal and Pakistan finding themselves towards the bottom of the list. Iraqis, unsurprisingly, are expected to jump through a lot of hoops to travel abroad, and have access to just 31 countries visa-free. And the country with the most restrictions? Afghanistan, whose people have passport-only entry to 28 nations around the world.

It’s not really an island, it’s actually what geologists call a “mud volcano,” which is caused by the pressure of sediment breaking up out from underneath the seabed. Basically an island of sand and mud, the mud volcano could last for anywhere from a couple of months to a few years, meaning it’s not here to stay long-term.According to local reporter Bahram Baloch, the island is about 250 to 300 feet in length, and about 60 to 70 feet above the water. You can walk on it, visitors to the island have also said that it is emitting flammable gas.

Within half an hour of the earthquake, inquisitive locals flocked to the island, which according to Rashid Tabrez, the director-general of the Karachi-based National Institute of Oceanography, is the fourth in the region since 1945. Geologists attribute that to the continuing process of continental drift that originally brought the Indian subcontinent to collide with Eurasia. In fact, 700 kilometers to the east of this new mud volcano lies the Makran coast, an area characterized by high seismic activity, and home to several other mud volcanoes.

While early explorers may have spent countless weeks plotting their journeys on maps and charting the best course to get to their destination, it seems many modern day travelers don’t have a clue about where they’re actually going.

A new study has found massive numbers of travelers can’t find their vacation destination on a world map. When asked where Cyprus was located, 53% of respondents were stumped, pointing to countries like Greece instead. This is despite having traveled to the Mediterranean island within the past year. Turkey also had recent visitors scratching their heads, with around half of those surveyed hard-pressed to locate the nearly 1,000 mile long country on an atlas.What’s most bizarre, however, is those people who seemed to have trouble locating their own country on a map. When asked where France was, a surprising 14% of French respondents pointed to their northern neighbor Belgium.

But perhaps we shouldn’t be so hard on the French. After all, remember this famous gaffe a few years back, when a Miss Teen USA contestant was asked why a fifth of Americans couldn’t locate the US on a world map?

But it’s not just beauty pageant contestants that are stumped by geography. Even politicians can get tripped up, like in this interview where John McCain refers to the problems at the Iraq/Pakistan border…which doesn’t exactly exist.

And then there was the time that President Obama managed to visit all corners of the US, including “about 57 states”.

Do you think it matters that so many people are confused by world geography? Or is understanding maps irrelevant in this day and age of GPS and technology?
